May 10, 2019May 10, 201905/10/19In Visual Studio 2019 you can target both Windows and Linux from the comfort of a single IDE. In Visual Studio 2019 version 16.1 Preview 3 we announced several new features specific to the Linux Workload: native support for the Windows Subsystem for Linux (WSL),
May 8, 2019May 8, 201905/8/19In Visual Studio 2019 version 16.1 Preview 3 we have integrated AddressSanitizer (ASan) into Visual Studio for Linux projects. ASan is a runtime memory error detector for C/C++ that catches the following errors:
Use after free (dangling pointer reference)
Heap buffer overflow
Stack buffer overflow
Use after return
Use after scope
Initialization order bugs
You can enable ASan for MSBuild-based Linux projects and CMake projects that target a remote Linux system or WSL (Windows Subsystem for Linux).
May 7, 2019May 7, 201905/7/19In the latest Preview release of Visual Studio 2019 version 16.1, we’ve added two quick fixes to the Code Analysis experience focused around uninitialized variable checks. These quick fixes are available via the Quick Actions (lightbulb) menu on relevant lines, accessed by hovering over the line or squiggle,
May 3, 2019May 3, 201905/3/19The May 2019 update of the Visual Studio Code C/C++ extension is now available to C/C++ extension Insiders.

March 7, 2019Mar 7, 201903/7/19Visual Studio 2019 Preview 3 introduces a new feature to reduce the binary size of C++ exception handling (try/catch and automatic destructors) on x64. Dubbed FH4 (for __CxxFrameHandler4, see below), I developed new formatting and processing for data used for C++ exception handling that is ~60% smaller than the existing implementation resulting in overall binary reduction of up to 20% for programs with heavy usage of C++ exception handling.

The battle against concurrency bugs poses a serious challenge to C++ developers. The problem is exacerbated by the advent of multi-core and many-core architectures. To cope with the increasing complexity of multithreaded software, it is essential to employ better tools and processes to help developers adhere to proper locking discipline.
